Brigand Arms
The Brigade Mk-15 5.56 is a modern 5.56 NATO rifle that borrows design inspiration from classic battle-rifle aesthetics while keeping the ergonomics shooters know from AR-platform weapons. Built on the Makasi platform, this 16-inch rifle delivers a compact, maneuverable platform suitable for home defense, tactical training, or general rifle use. Its short stroke gas piston system and bufferless recoil design keep things running smooth and reliable, while the side-charging handle keeps your shooting hand where it belongs on the controls.
What makes the Mk-15 stand out is its practical blend of old-school and new-school features. The side-folding Para-style stock isn't just for show—it's anchored with a two-screw mounting system robust enough to shoot from both folded and deployed positions, so you're not sacrificing capability for portability. The 12-inch M-LOK handguard gives you clean, modern modularity for mounting lights, lasers, or whatever you need on the job. Ambidextrous takedown controls mean lefties and righties operate the rifle with equal ease.
Under the hood, you're looking at 7075-T6 aluminum upper and lower receivers finished in Cerakote, a 4150 Chrome-Moly Vanadium Nitride barrel with a 1:7 twist, and a Mil-Spec fire control group. The muzzle is threaded 1/2x28 and sports a Brigade three-prong device. Magazines are standard AR15/M4 pattern, so ammunition supply isn't an issue. This is a rifle built to run hard and last.
Whether you're setting up a truck gun, a home defense carbine, or a compact range rifle, the Mk-15 brings solid engineering and thoughtful design to a platform that's proven itself a thousand times over.

Yes. The Para-style folding stock is mounted with a two-screw system that's robust enough to safely fire both with the stock deployed and folded, giving you flexibility for vehicle use or confined spaces.
No, it's non-reciprocating, so it stays in place while you fire and doesn't require mounting on a scope rail.
